About the campaign

Children who are unable to hear have problem learning to speak. They have fewer opportunities for education and difficulty keeping up with their age group – especially in developing countries. With the 4EARS campaign the Hear the World Foundation raises awareness for the underestimated topics of hearing and hearing loss. In the context of the campaign selected partners make a donation to the foundation for every hearing test conducted in one of their stores.

With these donations Hear the World provides hearing healthcare to children in need with hearing loss giving them the opportunity for better hearing and the chance at a better future.

You can help too! Do a hearing test at one of our participating partner stores today and make your contribution towards ensuring that even more children receive the chance of developing to their full potential.


Every visit at one of our partner stores will give a child with an untreated hearing loss the chance at a better quality of life. This happens in four steps:

  • Get your hearing tested at one of our partner stores.

  • Our partner makes a donation to the Hear the World Foundation

  • While you get the appropriate hearing solution...

  • ...the funds donated provide hearing healthcare to children in need.

The protagonists of the campaign

All the kids participating in the 4EARS campaign are children of Sonova employees. In this way they support children in need with hearing loss, a great extension of the Sonova employee engagement program for Hear the World. Meet our ten little stars.
